alanine/zea mays

Alanine aminotransferase (AlaAT, EC 2.6.1.2) and glycine aminotransferase (GlyAT, EC 2.6.1.4), two different enzymes catalyzing transamination reactions with L-alanine as the amino-acid substrate, were examined in maize in which alanine participates substantially in nitrogen transport. Preparative

Effect of spermaceti oil, cod-liver oil and corn oil on the content of total, direct and indirect bilirubin, on the activity of transaminase, alkaline phosphatase and colloid resistance was studied in three animal species (rabbits, guinea-pigs and albino rats) during 120 days (90 days of

Two Gram-stain-positive bacterial strains, designated as 5L6T and 6L6, isolated from seeds of hybrid maize (Zea mays L., Jingke 968) were investigated using a polyphasic taxonomic approach. The cells were aerobic, motile, endospore-forming and rod-shaped. Phylogenetic analysis based on 16S rRNA gene

A novel yellow-pigmented, aerobic, rod-shaped, non-motile bacterium, designated strain CCMF41T, was isolated from rhizosphere soil of maize (Zea mays) collected in Wufeng District, Taichung, Taiwan. Strain CC-MF41T exhibited 16S rRNA gene sequence similarity of 97.5, 97.3, 97.2 and 97.1% to

BACKGROUND There is controversy regarding whether increasing isolated soy protein (ISP) with or without flaxseed oil (FO), as functional foods, would lead to reduce muscle catabolism and cachexia in burn patients. METHODS One hundred and eighty-eight patients were assessed for eligibility in this

The insecticides mirex and chlordecone have previously been found to suppress the biliary excretion of a wide variety of compounds. In the present studies, the effects of mirex, chlordecone, and phenobarbital on the uptake of two endogenous organic anions, estradiol-17 beta(beta-D-glucuronide)

The Lluta Valley in Northern Chile is an important agricultural area affected by both salinity and boron (B) toxicity. Zea mays L. amylacea, an ecotype arisen because of the seed selection practiced in this valley, shows a high tolerance to salt and B levels. In the present study the

The isoenzyme glutathione S-transferase (GST) I from maize (Zea mays) was cloned and expressed in Escherichia coli, and its catalytic mechanism was investigated by site-directed mutagenesis and dynamic studies. The results showed that the enzyme promotes proton dissociation from the GSH thiol and

Major nutritional and agronomical issues relating to maize (Zea mays) grains depend on the vitreousness/hardness of its endosperm. To identify the corresponding molecular and cellular mechanisms, most studies have been conducted on opaque/floury mutants, and recently on Quality Protein Maize, a

Zea mays Brittle1-1 (ZmBT1-1) is an essential component of the starch biosynthetic machinery in maize endosperms, enabling ADPglucose transport from cytosol to amyloplast in exchange for AMP or ADP. Although ZmBT1-1 has been long considered to be an amyloplast-specific marker, evidence has

Dexamethasone (DEXA) administration has been associated with serum alanine aminotransferase (ALT) elevations that may result from enhanced ALT expression. The aim of our current study was to compare liver vs. serum ALT activity and to examine the onset of any hepatocellular changes. Groups of 4 male

Because in the phloem sap of maize (Zea mays L.) leaves a quarter of the total amino nitrogen can be found as alanine, the capacity of a de novo synthesis of alanine from 3-phosphoglycerate (3-PGA) was studied with isolated bundle sheath (BS) strands of maize. Inasmuch as these cells have retained

The activity of L-Alanine: 2-oxoglutarate aminotransferase (E.C. 2.6.1.2) has been studied in maize (Zea mays) embryo. Crude extracts were fractioned with ammoniun sulfate to obtain low activity preparations of other aminotransferases present in crude extracts. The enzyme shows normal hyperbolic

The homodimeric alcohol dehydrogenase gene produce of maize (Zea mays L.) Adh1-1S1108 mutation was purified and compared with the parental Adh1-1S enzyme. The mutant alcohol dehydrogenase activity had pH optima and substrate specificity similar to those of the parental enzyme, but exhibited somewhat

Carbon-13 nuclear magnetic resonance (NMR) spectroscopy has been applied to the direct observation of acetate and pyruvate metabolism in suspension cultures of Zea mays (var Black Mexican Sweet). Growth of the corn cells in the presence of 2 millimolar [2-(13)C]acetate resulted in a rapid uptake of
